Stationary Flow Meter
for Pipes and Open Channels
Q-Eye PSC MT
Q-Eye PSC MT
The Q-Eye PSC MT permanent velocity area flow meter is
designed for applications in full or partially full pipes
100 - 2000 mm (4 – 80 inches) in diameter, or open channels with flow depths 40 – 2000 mm (1,5 - 80 inches).
It uses advanced Doppler profiling technology to directly measure velocity profiles making it the best choice
for sites with non-uniform, rapidly changing, backwatered, near zero, negative or reverse flow conditions.
This eliminates the need for on-site calibration, thereby
reducing significantly the cost of installation.
Combined with an integral upward looking ultrasonic
or a secondary external pressure sensor (optional) for
determining the depth, the meter is using a numerical
model for averaged velocity in the entire cross section
and the continuity equation to calculate flow.
Profiling Technology
Pulsed wave Doppler systems use a transducer that transmits short acoustic pulses. The received echo is rangegated to provide velocity measurements selectively from
a small segment along the acoustic beam, step by step
over the entire velocity profile.
Reflections of particles in other areas do not have any
influence on the velocity measurement. Additionally the
1 MHz sensor provides higher data resolution by detecting smaller particles.

Q-Eye PSC MT (Insertion)
The system can be equipped with up to 4 analog
inputs, up to 4 analog outputs, 2 digital outputs and 4
relays.
Data Transmission
Automatic data transmission via GPRS communication
is an option and can be used worldwide. The logged
data can be sent to any host computer (FTP-Server)
or to HydroVision’s web-based HydroCenter at a userselectable frequency (typically 4 times a day, once a day
or once a week). Alternatively, WLAN and Ethernet are
available.

Technical Information
Q-Eye PSC MT
Transmitter
Parameterization of the measurement site and data visualization is easily possible using the standard web-browser of your
already existing smartphone, tablet PC or notebook – there is
no need for any additional software or App. The interface is
graphical and menu-driven for rapid comissioning. Your flow
meter can be accessed from anywhere - anytime 24/7.
Software
Insertion Type
Q-Eye PSC MT is a major improvement in open channel flow
measurement. It’s the latest entry in the HydroVision family of
high accuracy metering products. This flow computer incorporates all of the required algorithms and software to ensure
accuracy and repeatability. The IP65 (NEMA 4X) compact flow
display computer has a 4x20 alphanumeric LCD display and a 4
button keypad. All configuration data and measured and calculated data are stored inside an 16GB Micro-SD card. It controls the measurements, calculates the flow rate and provides
freely programmable current outputs, status alarm, frequency
outputs and totalizer readings.

Sensors
Mounting Systems
Mounting Plate, Spring Ring and
Scissors Rings
The submergible depts and velocity sensor which measures
only 15x25x108 mm is the smallest sensor of this type currently
available. A low profile means less interference, which results
in more accurate velocity measurements, especially in low-flow
situatuons. The insertion sensor is used, when the pipe is accessible from the outside only. For use in full pipes or partially
full pipes when used in conjunction with an ultrasonic pressure
depth sensor. These sensors can be installed into existing pipework through an 2“ ball valve.
All sensors can be attached to a mounting plate, spring and scissors rings to install the sensors in minutes and reducing time in
the manhole. The sensor is first attached to a carrier and can
than slide onto any of the compatible mounting systems. This
maintains a height, suitable for measuring flow rates and velocities at very low water levels. To install the sensors in rectangular, trapezoidal or earthen channels, we recommend the sensor mounting plate. Stainless steel spring rings simplify sensor
installation in cylindrical pipes. 6 standard diameter sizes from
200 mm (8 inches) to 600 mm (24 inches) are available. You can
install the sensor and fasten the cable to the downstream edge
of the ring in place before you enter the manhole. The self-expanding device is tight by expanding the band for a friction fit
inside the pipe. The adjustable scissors ring is installed in large
diameter pipes from 500 mm (20 inches) to 1450 mm (57 inches)
in diameter. It consists of a base section, one or more pairs of
extensions to fit the size of the pipe and a scissors mechanism.
Web-based data logging
HydroVision’s web-based data logging system enables real-time
remote access to your data.
